[0038] The first embodiment of the present invention, such as figure 2 As shown, a method for real-time presentation of a group call state in a PTT session, comprising the following steps:

[0039] Step 101: After the group call is initiated, the PTT switching unit sends the current group member call status to the MSC through the No. 7 signaling. The content carried in the No. 7 signaling includes the group member phone number and the corresponding group member call status.

[0040] Step 102, MSC sends the call status of the corresponding group member to all group members in the group call through the progress message in the L3 signaling according to the group member phone number obtained from the PTT switching unit as the sending address, so that All group members know the initial conversation states of all group members involved in the group call except themselves.

[0041] Step 103. When the call state of any group member changes, the PTT switching unit sends the changed...

[0060] In the third embodiment of the present invention, a system for presenting the status of a group call in a PTT session in real time, such as Figure 5 As shown, the transmission of group and presence messages in the prior art is represented by a dotted line double-headed arrow, and call signaling and voice exchange are represented by a solid line double-headed arrow. Delivery is indicated by a one-way double-row dashed arrow, and the system includes:

[0061] The mobile call terminal is used as a group member to initiate or receive a group call, and at the same time receive the progress message carrying the call status of the group member sent by the MSC, and analyze the group member from the progress message according to the agreed data format The call status of is displayed locally;

[0062] The PTT exchange unit is used to send the call status of the group members to the MSC through the No. 7 signaling, because the PTT exchange unit grasps the call status of all grou...

Abstract

The invention discloses a method and a system for presenting a group conversation state in a PTT session in real time. The method comprises the following steps: after a group call is started, a PTT exchange unit transmits conversation states of the current group members to an MSC; the MSC transmits the conversation states of the group members to all group members in group conversation; and when the conversation state of any group member is changed, the PTT exchange unit informs the conversation state of the group member with the changed conversation state to other group members in the group conversation by the MSC. The group members in the current group conversation can master the conversation states of other group members in real time. The scheme enriches the functions of group users andstrengthens the experience of the group users by reasonably and simply extending the 3GPP standard in the prior art. Manufacturers of network equipment and terminal equipment just support the extended protocol in the software of the equipment without carrying out hardware investment, thereby the realization cost is lower.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and system for real-time presentation of group call status in a PTT session. Background technique [0002] PTT (Push To Talk) is to use a mobile phone with corresponding functions as a walkie-talkie. It is a half-duplex communication method. This kind of mobile phone has an intercom button. After the user presses it, he can communicate with other users. Or group calls. PTT conversation is also called group talk, which is to realize push-to-talk through public mobile cellular network technology. The biggest feature of this technology is to use the current public mobile network to provide group intercom function. [0003] This technical solution has a mature technical solution implementation and commercial operation mode in many countries at present, and it is applied in 2G and 3G. Commercial PTT session implementation solutions are divided into two c...
